My step sister went for her dating ultrasound on Monday, she should have been almost 8 weeks along. They have been doing IVF treatments for almost 2 years and this is the first positive they have had. Unfortunately the babies had no heart beats ( twins ) . We are all devastated for them

She and I are not close since our parents married when we were adults , so I dont know any details about the scan or what they told her. She had come to me for pregnancy advice and to share her joy but nothing since her loss( which can be expected for sure !)
Our gender reveal to our families is next week and I absolutely do not know how to handle our news since we were planning a big family get together. Should we do it just more private now, no get together ? I dont want to alienate her but I DO NOT want to make her feel worse. I feel like our family is so sad that maybe we should just hold onto our news for a while and not bring it up at all

Also is there anything I can do besides offer her support and give her her privacy until shes ready to reach out ?
TIA !
Re: Advice needed re: Step Sister ( Loss mentioned )
As for the reveal, do people already know its happening? That impacts my decision.
О Привязать! Z!

I honestly wouldn't know how to approach it maybe ask her biological parent how she would feel (as they would probably know her best). Take it from there.... Wish I was more helpful! T&P to your step sister.
With respect to the gender reveal . . . did you already tell your family you wanted to do a get-together? If not, then I might make it a smaller affair. That doesn't mean it can't be a celebration, but maybe fewer people? Or make the gender reveal a very small part of an afternoon/evening together?
All I can say is that I was VERY raw after my miscarriage, and we hadn't even been trying as long as 2 years. I was at a big family get-together about 2.5-3 months after the miscarriage, and it was hard for me to just see a cousin who was pregnant. I can't imagine being able to handle a pregnancy related party at that point.
As for the gender reveal I think we will just wait a while to announce to the families. It is going to be hard on all of us to have a celebration so soon and when we do decide to announce I will be sure to let her decide how involved to be.
Thank you all for your suggestions ! Sometimes its hard to see all aspects when your in the middle of it all !
